Blessed are those who hunger and thirst for righteousness, for they shall be filled. --Matthew 5:6
It may be said without qualification that every man is as holy and as full of the Spirit as he wants to be. He may not be as full as he wishes he were, but he is most certainly as full as he wants to be.
Our Lord placed this beyond dispute when He said, "Blessed are they which do hunger and thirst after righteousness: for they shall be filled." Hunger and thirst are physical sensations which, in their acute stages, may become real pain. It has been the experience of countless seekers after God that when their desires became a pain they were suddenly and wonderfully filled. The problem is not to persuade God to fill us, but to want God sufficiently to permit Him to do so. The average Christian is so cold and so contented with His wretched condition that there is no vacuum of desire into which the blessed Spirit can rush in satisfying fullness. Born After Midnight, 8.
